Application filed October 13, 1882. (No model.)

To all whom fit may concern:

Be it known that I, CHARLES I -I. BLANCH- ARD, of Batavia, Ohio, have made a new and useful Improvement in Automatic Fans, ot' which the following is a full, clear, and exact description, reference being had to the annexed drawings, making part of this specication, in which- Figure l is a view in perspective of the improvement in position 5 and Figs. 2 and 3, details, being sectional views taken through the casin g. Fig. 2 shows the arrangement when a cord and weight are used, and Fig. 3 when a spring is used.

The same letters denote the same parts.

The present invention is an improvement in fans used to agitate the air in sleeping-apartments, sitting and dining rooms, workshops, and other places, and for driving away iies, mosquitoes, &c.

It consists of a revolving fan actuated by a cord and weight, the fan being connected with a casing or frame containing gearing for operating the fan, and the fan and casing being suspended by a vertically-adjustable connection from an overhead support.

A,Fig. l, represents the fan, having one or more vanes, ce a'. It is attached to a shaft, B, which in turn is supported in or upheld by a casing or frame, G. This casing or frame is suspended from an overhead fixture-say, the ceiling D.

The suspending device E is constructed so as to make the fan vertically adjustable; and to this end the suspensory E may be in two parts, c and c', the lower part, c, being movable upward an d downward upon the upper part,

e', and xed at any point thereon by means of the set-screw c2.

A weight, F, is suspended from a cord, Gr, which passes over bearings H H, and thence around a drum, I, upon the shaft J. This lastnamed shaft rotates in bearings in the casing O, and a train of wheels, K L, communicates the motion of the shaft VJ to the fan-shaft B.

In operation, the weight F, by applying a key to the shaft J at j, iswound up toward the Y the shaft B,the casing C, the vertically-adjustable suspensory E, the weight F, the cord G, the drum I, the shaft J, and the train L K, substantially as described.

2. The combination ot' the revolving fauA, the casing O, the shaft B, and the rods c e', the rod e being vertically adjustable upon the rod c', substantially as described.

3. A revolving fan, A, actuated by a train of gearing, said fan and train having a vertically-adjustable connection with an overhead fixture, D.

4. The revolving fan A, having the removable fringes M, as and for the purpose described.
